Re: Solar panel
Surely it would not get any hotter than the 82 degrees most boilers can reach i mean all the safety devices in terms of thermostats are there to make sure that the water in pipe work NEVER gets past 95 degrees celcius. This being because under pressure its possible for water not to turn to steam until way past 100 degrees celcius and if someone opened that temp water to atmophere they would probably die as it would instantly turn to steam. So it cannot be for temperature reasons there must be another reason for not using soft solder.
